What I think you should do is get out of this relationship immediately. Your fiance is insecure and controlling. I’m guessing that he was badly burned in his prior relationships and now thinks that all women are cheaters. Yes, that makes his anxiety somewhat understandable. But it doesn’t give him the right to be constantly grilling you, monitoring your phone calls, and threatening you. That table going over should have been the very last straw!
You have done nothing wrong. You don’t deserve to be treated this way. No one does. You shouldn’t have to constantly prove your innocence to a man who says he loves you. You are a working woman which means you will have work relationships that need your attention. I hope you also have friends and family to talk to and spend time with. That’s only normal.
Marrying him will mean a lifetime of dealing with accusations and fear. You deserve better. If you have children, they shouldn’t have this kind of destructive relationship as a role model for adult behavior and marriage.

Erase this message from your logs. Men like your fiance sometimes get very, very angry when they discover that their girlfriend has looked for some help.
I wish you well.
